Option "RegistryDwords" "EnableBrightnessControl=1" In xorg.conf seemed to help it so now I can use the /etc/acpi I listed in pastebin and it works...
But when I use the F keys the contrast seems to be off, it's not as nice as when I use nvidia-settings which does 'All Channels' and makes it look better...
So this what I use right now;
Is there any way to convert this so it changes all the channels when it adjusts?
nvidia-settings --assign GreenBrightness=0.1
nvidia-settings --assign RedBrightness=0.1
nvidia-settings --assign BlueBrightness=0.1
